Hi Siarhei, i can not agree with everything you say. 1. I think that user may deal with cpu frequency settings, there are many examples to do it. I could not predict if there would be people wanting their boards working on batery or not
2. There is no effective way to do it, but kernel hacking, or using kernel command line parameters. If I hard code this settings in u-boot or kernel, users will not be able to change easily themselfs. This will cause other kind of problems. Some people will tell that i am a dirty bastard who does not give them freedom to do what they want. 3. Yes I agree with that, and I will do it in shortly 4. also with that, this one is done 5. Siarhei keep in mind that only I work on this image, and the goal is that everyone can build it alone. p.s I will appreciate any help :) ~Best Dimitar On Monday, December 16, 2013 6:44:03 AM UTC+2, Siarhei Siamashka wrote: > > Hello, > > On this weekend, I tried to check the Debian Linux image > provided for A10-OLinuXino-Lime at > > > http://olimex.wordpress.com/2013/12/13/building-debian-linux-image-for-a10-olinuxino-lime-with-kernel-3-4-67/ > > > As can be seen from the user comments in that blog post, it > happens to be very far from perfect.
